Document Summary

Shock: locomotion, production & storage of red blood cells. Also white blood cells: storage of minerals. Hydroxyapatite: growth at epiphysis, several factors affect. Stress: skeletal muscle pulls against bone, causing it to rebuild and become stronger. Femur: basic pattern found in 40k species of backbones animals. Skull: protects brain, location 4 senses, 30 pieces fuse into 22 bones & 6 ear bones, cranial capacity: 1350g, skull features. Stoop, squat, turn / nod, twist shoulders and hips: vertebrae sections. Have holes in sides to allow blood vessels through. Provide path and protection of spinal cord and relate blood vessels, nerves. Degenerative disc; bulging disc; herniated disc; thinning disc degeneration with osteophyte formation; disc; inflammation; fusion. Rib cage: protects lungs and heart, flexible / shock absorber, composed of. Shoulder girdle: unique in humans and primates, composed of. Humerus: broad range of motion 360 degrees. Spiral due to twisting: hand, 8 wrist bones, 19 metacarpals and phalanges, opposable thumb.
